What Are The Three Sources Of Energy Exercise

Instead the body has three different systems of atp production.

What are the three sources of energy exercise.

The aerobic energy system is also known as the oxygen energy system and it uses both carbohydrates and fat in a slow energy burn. The extent to which these substrates contribute energy for exercise depends on the intensity and duration of exercise the level of exercise training the initial muscle. For example during heavy exercise the body s total energy expenditure may increase 25 times above expenditure at rest 2 the body uses carbohydrate fat and protein to provide necessary energy to sustain cellular activities both at rest and during exercise 3. Each system uses different starting fuels each provides atp at different.

Atp which stands for adenosine triphosphate is the sole source of energy for all human metabolism yet very little of this fuel is actually stored in the body. Although muscles and engines work in different ways they both convert chemical energy into energy of motion. The body uses 3 different systems to supply cells with the necessary atp to fuel energy needs. During exercise there are four major endogenous sources of energy.

Atp pc anaerobic glycolysis and aerobic phosphorylation. Muscles use the stored chemical energy of food we eat and convert that to heat and energy of motion kinetic energy. Most of the body s activities use a continuum of all three energy systems working together to ensure a constant supply of energy. Exercise poses a major challenge to the various bioenergetic pathways in the working muscle 2.

A motorbike engine uses the stored energy of petrol and converts it to heat and energy of motion kinetic energy.
